“…Ultimate resilience was the energy per unit volume necessary to cause failure. Good correlations of mean depth of penetration (MDP) with material hardness and also with fatigue strength were also confirmed by Richman and McNaughton [4], Bedkowski et al [5], Heathcock et al [6], and Bogachev and Mints [7].…”

“…However, they usually exhibit a poor sliding wear and cavitation erosion resistance which may result in material transfer, mechanical mixing and oxidation between sliding bodies and cavitation erosion in machinery such as hydro-turbines, pumps and valves. A possible solution to the above-mentioned wear problems is to coat the austenitic stainless steel parts by a layer of martensitic stainless steel with a good combination of corrosion resistance and high hardness and erosion resistance using laser cladding process [1][2][3][4].…”

The effect of cladding speed on phase constitution and properties of AISI 431 stainless steel laser deposited coatings Hemmati, I.; Ocelik, V.; De Hosson, J. Th. M. Take-down policy If you believe that this document breaches copyright please contact us providing details, and we will remove access to the work immediately and investigate your claim. Shorter processing time has given impetus to laser cladding technology and therefore in this research the AISI 431 martensitic stainless steel coatings are laser deposited at high cladding speeds, i.e. up to 117 mm/s. The analysis of phase constitution and functional properties of the coatings are performed by optical microscopy, Scanning Electron Microscopy (SEM), and hardness and sliding wear tests. The outcome of this research shows that an extreme refinement of the solidification structure will influence the phase constitution of the coatings by lowering the M s temperature and hence stabilizing the austenite which results in lower hardness values and increased wear rates. These results confirm that the structural refinement obtained by higher cladding speeds is not helpful for improving the hardness and wear properties of laser deposited martensitic stainless steel coatings.

“…4) Austenitic stainless steels such as 304 and 316 have been in use in hydraulic machinery because of` their resistance to cavitation erosion. [5][6][7] These austenitic stainless steels exhibit better erosion resistance compared to the 13/4 martensitic stainless steel. Cr-Mn-N stainless steels have potential to substitute these Cr-Ni-Mo stainless steels because of their lower cost and higher cavitation erosion resistance.…”

The effect of grain size on solid particle erosion and cavitation erosion of a nitrogen alloyed austenitic stainless steel has been investigated. Heat treatment of the steel at elevated temperatures results in an increase in grain size and thus modification in mechanical properties. Particle erosion tests were performed using an air jet erosion tester. An ultrasonic processor with a stationary specimen was used to investigate the cavitation erosion performance. The cavitation erosion rates were found to increase with the increase in grain size. The particle erosion rate shows no significant change with increase in grain size. The worn surfaces were examined to study the characteristic damage features using scanning electron microscope (SEM). The nitrogen alloyed austenitic stainless steel exhibited superior resistance to cavitation erosion and particle erosion than a 316L stainless steel. The hardness, yield strength and ultimate tensile strength of the steels are related with the erosion resistance.
